Qhov sib txawv tseem ceeb ntawm nuclear fusion thiab fission yog tias nuclear fusion yog kev sib xyaw ntawm ob lossis ntau lub atoms los tsim ib lub atom loj thaum nuclear fission yog kev faib cov atom loj rau hauv ob lossis me me atomic particles.

Nyob rau hauv physics, ib qho kev ua ib txwm muaj qhov sib npaug tab sis cov lus teb rov qab. Qhov no yog qhov kawg ntawm kev xav hauv physics; yog li ntawd, txhua qhov xwm txheej thiab kev ua haujlwm yeej ib txwm muaj cov tshuaj tiv thaiv sib txawv. Tsis tas li ntawd, qhov no yog lub hauv paus tseem ceeb ntawm nuclear fusion thiab nuclear fission cov tshuaj tiv thaiv ib yam nkaus. Cov no yog ob hom kev tawm tsam uas tso tawm qee lub zog. Hauv chemistry yooj yim, ib qho tsim cov atom me me thaum lwm tus sib txuas cov atoms los ua ib qho loj dua.

Nuclear Fusion yog dab tsi?

Nuclear fusion yog qhov sib xyaw ntawm ob lossis ntau lub atoms los tsim ib qho loj dua. Hom tshuaj tiv thaiv no tso cai rau cov atoms sib xyaw ua ke txhawm rau tsim cov atom loj dua nrog tus lej atomic ntau dua. Ib txoj hauv kev ntawm kev ua ib qho kev sib txuas ntawm nuclear yog los ntawm kev tso cai rau ob lossis ntau lub nuclei nyob ze ib leeg, uas ua rau muaj cov tshuaj tiv thaiv uas ua rau cov atoms lo ua ke thiab sib xyaw ua ib qho.

Ntxiv mus, nuclear fusion tshwm sim nyob rau hauv ib txwm muaj. Ib qho piv txwv zoo yog cov hnub qub hauv galaxy. Raws li kev xav, ntau lab lub hnub qub tau sib xyaw ua ib lub hnub qub loj heev, peb tam sim no hu ua lub hnub.

Nuclear Fission yog dab tsi?

Nuclear fission yog qhov ntxeev ntawm nuclear fusion. Nws yog kev faib cov atom loj rau hauv ob lossis ntau qhov me me. Txhawm rau tsim fission, muaj ob yam uas yuav tsum tau ua tiav:

1. Lub neutron qeeb heev (rau cov txheej txheem ntawm kev faib tawm)

2. Qhov tsawg kawg nkaus ntawm cov khoom tshwj xeeb (rau fission tshwm sim)

Tsis tas li ntawd, qhov tsawg kawg nkaus ntawm cov khoom yog qhov tseem ceeb, uas nyob ntawm lub neutron nws tus kheej. Nuclear fission tsis tshwm sim nyob rau hauv qhov zoo li fusion ua.

Qhov txawv ntawm Nuclear Fusion thiab Fission yog dab tsi?

Ob qho tib si nuclear fusion thiab fission tso tawm ntau heev thiab muaj zog ntawm lub zog thiab ob leeg sib koom tib lub zog, uas yog lub atom nws tus kheej. Qhov sib txawv tseem ceeb ntawm nuclear fusion thiab fission yog tias nuclear fusion yog kev sib xyaw ntawm ob lossis ntau lub atoms los tsim ib lub atom loj thaum nuclear fission yog kev faib cov atom loj rau hauv ob lossis me me atomic particles. Ntxiv mus, nuclear fusion tshwm sim lawm, tab sis nuclear fission tsis.

Summary – Nuclear Fusion vs Fission

Ob leeg nuclear fusion thiab fission tso tawm ntau heev thiab muaj zog ntawm lub zog thiab ob leeg sib koom tib lub zog, uas yog lub atom nws tus kheej. Qhov sib txawv tseem ceeb ntawm nuclear fusion thiab fission yog tias nuclear fusion yog kev sib xyaw ntawm 2 lossis ntau dua atoms los tsim 1 lub atom loj thaum nuclear fission yog kev faib cov atom loj rau hauv 2 lossis me me atomic particles.
